In Fig. 1, A is the body or tub, which is of scoop form. B is the bale from which the tub is suspended,-and attached at such point, as at C, so that the greatest weight of the tub, when empty, is in the direction of D. Thus its own weight will always keep it in upright position. But when filled with any material the greatest weight will be on the opposite side of the bale say at the point E-hence, when filled, will discharge or dump itself as soon as detached, after .Which the weight of the tub will immediately bring it into upright position again. In Figs. 1 and 2, F is the latch which extends around the tub and is hinged at the back, as shown at G G, and provided with recesses or Witnesses A. M. DEDERIOK, JAMES RORABAGK.
